Application led August 16, 1924. Serial No. 732,502.

This invention relates in general to metal pails and covers, and has for its object to' provide a device of this character wherein the cover is fastened to the pail in such a novel and peculiar manner as to leave a maximum space at the top of the pail and yet provide for effective closure.

Another important object of the invention resides in the provision of means facilitating the opening of the pail, that is, the removal' of the cover, without necessitating the employment of any tools or devices other than those provided on the pail and cover and while saving the cover and the pail from breakage or distortion so as to permit the ready replacement of the cover and resealf ing of the pail.

A further object is to provide an arrangement whereby. the pail may be effectively sealed to prevent dilution of the contents thereof or the substitution of inferior contents for those originally contained therein.

Other objects and advantages reside in certain novel features of construction, yarrangement and combination of parts which will be hereinafter more fully described and particularly pointed out in the appended claims, reference being hadto the accompanying drawings forming a part of this specicatin, and in which Figure 1 is a view in elevation of a pail and cover embodying the present invention, Figure 2 is a view 1n vertical section taken' on the line 2-2 of Figure 1,

Figure 3 is a fragmentary perspective view illustrating the cover and pail immediately after the cover has been removed from the pail or'detached from the top thereof,

Figure 5 is a view in horizontalsection on the line 5-5 of Figure 4. y

Referring to the drawingsthe numeral designates the body portion of the pail, the Y bottom of which is closed and the top of which is open. Preferably the pail is ofthe type designed to be stacked, the bottom being reduced and being adapted to be fitted in the recess or seat providedftherefor in the top of the next lower pail when the pails are stacked. Of course'when the pails, are stacked, each ail has a cover 11 fitted -thereon and it is t e, cover that provides the recess or seat Lhich receives the lower end of alpail.

The' means employed for securing each cover to its pail is designed with reference to the capacity of the pail to be stacked, that is, this securing means is of such a character as to provide'a seat or recess in the top of maximum area since it lis not practical to -reduce the lower end of the pail to any great extent. An outwardly extending reinforcing rib or corrugation 12 is provided adjacent the upper end of the pail and extends circumferentially therearound. Above the corrugation 12 the upper end of the pail is formed with an outwardly extending curved Hange 13, the extremity of which is bent inwardly and upwardly against the underside of the Harige, as indicated at 14. A sealing member 15 is received on the curved top surface vof the Harige` 13 which provides a seat for the sealing member and when the cover 11 is applied to thep'ail this sealing member is compressed and hermetically seals the container. rThe cover 11 is formed with an upwardly extended and curved peripheral Hange 16, the extremity of the Harige 16 being curved inwardly, as at 17 and engaging under the shoulder 18 presented by the edge of the Hange 13 when the cover 11 is applied to the pail. The cover 11 and its Hange 16 is constructed of resilient metal and the pail may also be constructed of metal having some degree of resiliency. The resilient nature of the Hange 16 enables the same to be cammed over the rounded top surface of the Hange 13 and to snap under the shoulder .18 ofthe Harige 13 when the cover is applied to the pail. A number of lips 20 are iritegrally formed f with the Hange 16 of the cover at intervals around the pail and when the cover is applied to the pail these lips' assume the position illustrated in Figures 2 and 4. Each lip 20 is provided with an Iaperture 21. The lips 20 are designed to coact with a small spike, nail or other pointed tool 22, the tool being inserted through the opening 21 of the lip 20 and being swung about the crest of the Hange 16 p of the pail which is spot-Welded to the body portion thereof is provided with an Vout- I struck loop 26 defining a socket 27 of the tool 22. This socket 27 is located so near to the top of the pail-that the tool 22 cannot drop out of or be removed from the socket when the pail is inverted after the cover 11 has been applied. The loop 26 is made of a thin section of metal and this enables the ready removal of the tool 22 when the pail is to be opened since the lower end of the tool-22 may be grasped and the tool rocked or pulled to tear or break the metal of the loop 26.

The loop 26 and one of the adjacent lips 20 provide in conjunction with a wire 28 and seal 29 a sealing arrangement for preventing undetected removal of the cover 1l from the pail and consequently this arrangement prevents dilution of the contents of the pail or substitution of inferior contents for the original contents of the pail. As shown in the drawings the sealing wire or element 28 is passed through the opening 21 of the lip 20 and through the socket 27 and the ends of the wire are united by the sealing lead 29.

I claim:

l. A pail having its body'portion provided with an outwardly extending flange at its upper end, said flange being rounded and having its edge presenting a shoulder, a cover having an upwardly extending and curved peripheral flange, the edge of the flange of the cover being curved inwardly and being engageable with the shoulder of the flange of the pail inassembly, an apertured lip carried by the flange of the cover` and extending downwardly and outwardly loo from the flanges and a loop carried by the body portion of the pailv just below and within the limits of the flanges of the body portion of the pail and of the cover, said loop defining a vertically disposed socket adapted to support a tool which is adapted to co-act with the apertured lip to facilitate removal of the cover, said apertured lip and loop also being adapted to receive the wire of a seal, the outwardly projecting and interengaging flanges serving to protect the loop, seal and tool.

2. A pail having a body portion and a cover, interengaging members between the cover and the body portion for securing the cover to the body, a portion of said members projecting outwardly beyond the periphery of the pail, a loop carried by the body portion and defining a socket, the loop being made of a thin frangible section of metal and being located adjacent and below the members, and a tool carried in the loop and having a head preventing downward displacement by virtue of its engagement with the loop, the head of the tool be1ng engageable with the interengaging members of the pail and cover to prevent the tool from dropping out of the loop when the container is inverted after the cover has been applied, said tool being adapted to co-operate with an apertured lip carried on one of the interengaging members to effect the removal of the cover when the tool has been removed from the pail by racturing or tearing the p` SMITH MADISON, JOHNSON.
